Recent space and geological discoveries include unexplained compounds on Pluto and Titan, identified repeating radio signals, deep space sugar molecule, Earth's potential Sun avoidance, and more.
Astronomers detected an atmosphere on LHS 1140b, a super-Earth in a habitable zone 49 light-years from Earth, by analyzing escaping helium. While no evidence of life exists, the discovery makes LHS 1140b a prime target for astrobiology studies.
Scientists using the James Webb Space Telescope have detected gases, including dimethyl sulfide (DMS), on exoplanet K2-18b that are linked to biological activity on Earth. While the signal is strong, it's not yet confirmed as life, with researchers awaiting further data to rule out non-biological explanations.
